In this paper, we analyze the performance of a single hop CDMA based wireless sensor network (WSN) using receiving antenna diversity at sink in terms of outage probability and bit error rate (BER). Correlation amongst signal and interferers is considered in large scale fading environment. We assume each node is power controlled while antenna diversity is present only at the sink. Energy consumption...
This paper evaluates the end-to-end outage probability of a CDMA based static multi-hop wireless sensor network (WSN) in shadowed environment. An interference model for multi-hop is presented considering correlation amongst interferers. Three different information delivery mechanisms are studied using regenerative relays with or without error correction capability. Outage probability for each mechanism...
In this paper, outage performance of a frequency planned cognitive radio network has been studied. We consider dynamic spectrum sharing with spectrum underlay approach. Both secondary and primary users will access the same spectrum but primary user will be oblivious to the presence of cognitive user. Secondary users can change their radio parameters adaptively on demand. We consider correlation amongst...
In this paper, the performance of a Cognitive Radio (CR) CDMA networks is analyzed in uplink. More precisely, we develop a simulation testbed for analyzing performances of a CR user and a primary user (PU) in a single cell. CR users belong to infrastructure less ad hoc network, which coexist with a primary radio network (PRN). CR users or secondary users (SUs) are considered to form pair wise links...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) with layered architecture in terms of energy consumption for successful transmission of data packets, considering only correlation among interferers in shadowed environment. We consider a model of interference at the sink for a layered architecture of CDMA based WSN with two kinds of interference, multiple access interference...
The paper evaluates the performance of a CDMA based wireless sensor networks (WSN) in terms of outage probability and BER, considering correlation among interferers in shadowed environment. An appropriate model for the interference power, outage and BER are presented for a single hop communication. Detection probability is also evaluated in shadowed environment. The effects of node density, minimum...
